Aniline Point Apparatus

Description

• Method A: As per IP 12 & IS 1448 (P-3), ASTM D 611 method a complete with jacket. Aniline point is used to
• characterize pure hydrocarbons and to indicate the aromatic content of hydrocarbon mixtures. Equal volumes of
• aniline and sample or sample plus n heptane are stirred together while being heated at a controlled rate. r the
• two phases become miscible, the mixture is cooled at a controlled rate and the temperature at which the two phases
• separate is the aniline point or mixed aniline point of the sample.
• Method B: The aniline point method B is a thin-film procedure used to determine the aniline point of hydrocarbon
• solvents and petroleum products that are too dark to test using method A of ASTM D611. The method involves:
•  Mixing equal parts of aniline and the sample or sample plus n-heptane in a test tube.
•  Heatng the mixture at a controlled rate while strring,
•  Cooling the mixture at a controlled rate, Recording the temperature at which the two phases separate as the aniline point.
